Alge, by W. H. Harvey.) FLORA OF TASMANIA. 303 
8. Dasya Feredayee (Harv.) ; caule elato glabro opaco cartilagineo decomposite ramosissimo, ramis 
lateralibus virgatis gracilibus quaquaversis iterum et iterum alterne divisis, minoribus nune virgatis sim- 
plicibus nunc ramosis attenuatis ramelliferis, ramellis roseis monosiphoniis undique insertis patentibus vel 
squarrosis ad apices densioribus dichotomo-multifidis axillis patentibus apice attenuatis, articulis ramellorum 
diametro 4—6-plo longioribus cylindraceis, ceramidiis . . .?—Harv. Alg. Exsie, n. 220. 
Var. 8; ramis ramulisque squarrosis.—Harv. Alg. Ezsic. n. 221. 
Has. In the Tamar, at and above Georgetown, Mrs. Fereday, ete. 
Frond 1-2 feet long or more, half a line to a line in diameter at base, set throughout with lateral branches 
spreading in all directions, the lower long, the upper gradually shorter. Branches virgate, three or four times 
alternately decompound, each set of branches more slender, generally straight and erecto-patent, sometimes squarrose 
and curved. All the larger branches are glabrous, the lesser ones but sparingly covered with ramelli, the penultimate 
ones alone thickly ramelliferous ; but different specimens differ greatly in the density and copiousness of the ramelli. 
Every part of the frond is inartieulate, coated with small cells. The ramelli are patent, sometimes squarrose, many 
times dichotomous, attenuated to the points, and their articulations are 3-6 times as long as broad. The colour is 
rosy-red, well preserved in drying. The substance is firm, and the plant may be immersed for some time in fresh- 
water without injury.—1 have not seen any fructification. 
I first saw some fine specimens of this plant in the collection of Mrs. Fereday, of Georgetown, to whom the 
species is dedicated, and afterwards I collected it in considerable abundance in the Tamar. It has also been sent in 
Mr. Gunn's later collections. 
9. Dasya Haffise (Harv.); caule elato villoso opaco cartilagineo decomposite plumoso-pinnato, 
ramis virgatis distichis subtripinnatis ramulisgue patentibus densissime ramelliferis, ramellis roseis undigue 
insertis sguarroso-crispatis dichotomo-multifidis axillis patentibus apice acutis vix attenuatis, articulis ramel- 
lorum diametro sesgui-subduplo-longioribus, ceramidiis sepe pinnulos ultimos terminantibus globosis ore 
porrecto densissime ramellis involucrato-vestitis, stichidiis minutis ovalibus mucronatis.—Harv. Alg. Exsic.

Disrrrs. First found at Western Port, Victoria, W. H.H. 
Frond 12-18 inches high, and nearly as much in expansion, with a principal undivided or once-forked stem, 
closely set throughout with patent lateral branches, the lowest of which are longest. These branches are distichous, 
or nearly so, and are twice or thrice plumoso-pinnate, the pinne and pinnules all patent. The pinne are of un- 
equal lengths, long and short intermixed ; the smaller ones are either simple or once pinnate, the larger two or three 
times decompound. The main branches at first are densely ramellose, but become bare with age; all the lesser 
branches generally retain their villosity. The pinne and pinnule are densely clothed m int, intricate, squar- 
rose ramelli, many times dichotomous, not much tapering, but acute at the points, their articulations short. Cera- 
midia generally terminate the shortest of the ramuli, and are hidden in a dense nest of ramelli, whioh bayer over 
even the walls of the ceramidium. Stichidia minute. Colour a rosy red, sometimes turning brown in drying. Sub- 
stance soft, but not gelatinous.— The specific name is in honour of Mrs. M Haffie, of Philip Island, T Port. 
The specimens from Table Cape are much injured, and in part denuded of ramelli, and may possibly belong to a 
different but closely allied species. 
10. Dasya Muelleri (Sond.) ; caule elato (pedali et ultra) crasso villis stipato subdichotomo, seg- 
mentis ramiferis, ramis secundariis longissimis (1-2-pedalibus) caule multo tenuioribus glabris corticatis 
simplicibus inferne seepe denudatis superne pulcherrime plumoso-pinnatis, pinnis alternis erebris horizonta- 
libus plus minus ecorticatis polysiphoniis iterum pinnulatis, pinnulis oligosiphoniis — ramelliferis, 
ramellis dichotomis attenuatis obtusis, articulis diametro 2-4-plo longioribus, ceramidiis magnis pedicellatis
